WebChromatography is a physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary (stationary phase) while the other (the mobile phase) moves in a definite direction. The effluent is the mobile phase leaving the column. WebWhat are the two phases of chromatography - The separation of a mixture is done by passing the solvent through a chromatographic paper which is called paper.
